Question
There was a leakage in the petrol tank. If 5litre of
petrol is leaked out per day then it would have lasted for 30 days. If the leakage was 7litre per day, then it would have lasted for only 24 days. For how many days would the petrol have lasted, if there is no leakage and it was completely used for the vehicle?Solution
Let x litre of petrol is used for transport purpose daily Then, (x + 5) × 30 = (x + 7) × 24 30x + 150 = 24x + 168 6x = 18 x = 3 Therefore, total quantity of oil = (3 + 5) × 30 = 240 litre Required number of days = 240/3 = 80 days
